It would be nice to know if it had ever flown (in a Whirlwind, nothing else used Peregrines did they?)
Didn't know Cosford had one, is it one of Steve Vizards pair? One is or was at the R-R Museum Derby... If Cosford does have one it was from a Whirly, Westlands had the lot, apart from the ones used for the R-R Vulture's in the Manchester's and Gloster's F9/37 second prototype L8002...
Oh and one was use in Rolls-Royce's test aircraft He 70G flying with a Peregrine engine...
